  5. I. Introduction • Why is the project being done? • -To correct short voltage sags (a few seconds) to maintain a stable voltage to critical loads. • Why is this important? • -The shutdown of critical loads due to short voltage sags can be costly.

  6. II. Primary Objective • Interface a flywheel to the AMPS with the ability to correct for voltage sags occurring on the AMPS. • Implement the design by Satish Samineni

  7. Secondary Objectives • Spin a flywheel • Communicate between converters • Operate each converter with its own PWM • Provide power to AMPS • Operation Manual

  8. III. Design Functionality • Organizational Chart • Block Diagram • Overall Circuit Schematic • Sub Circuit Schematics • Programming • Assembled • Documentation • Specifications

  9. Interface a flywheel to AMPS to correct for voltage sags on the system Spin a flywheel Provide power to AMPS Communicate between converters Operate a space vector PWM scheme Operate a sine–triangle PWM scheme Sag Status Program the switching times calculation Program matrix math functions Program a Phase locked loop Program the triangle wave Program the sine wave look up table Organizational Chart
